Pigmentation makeup method and makeup auxiliary using it, flood light and pack

ABSTRACT

The alleviation of the burden on the cosmetic decoration and the effect of making the subject to look thin can be easily accomplished by providing a technique of cosmetic decoration which easily obtains the same effect based on light and shade as the application of foundation, allows the beautiful state resulting from the cosmetic decoration to last for a fixed number of days without being impaired by water or perspiration, and produces a natural finish. 
     The method for cosmetic decoration according to this invention, in performing cosmetic decoration by resorting to the impartation of light and shade to the surface color of the skin, implements the cosmic decoration by causing the degree of pigment deposition in the area of the skin requiring to assume a darker color to be larger than in the other part of the skin thereby imparting light and shade to the surface color of the skin.

TECHNICAL FIELD

This invention relates to a technique for cosmetic decoration,particularly to a technique for cosmetic decoration intended to impartlight and shade to the surface color of the skin.

BACKGROUND OF THE INVENTION

As the items that heavily weigh among the matters of concern for women,cosmetic decoration and slimness may be cited.

The cosmetic decoration largely varies the impression of a person whohas used it. Of course, the object of this cosmetic decoration residesin satisfying the wish to be more beautiful. There are also times whenthe advantage of the change of the impression by cosmetic decorationmanifested in altering the mode of feeling Is longed for and evenmaterialized. From this point of view, the daily cosmetic decoration maywell be called an act which women can perform with enjoyment.

Meanwhile, however, the cosmetic decoration can form a large burden forwomen. In the present situation in which the cosmetic decoration isrecognized as what must be performed naturally, the sensation of burdeninflicted on women possibly grows excessively because the act ofperforming the cosmetic decoration everyday may well be said in a senseas an obligation laid on woman.

The elements of the cosmetic decoration under discussion include eyebrowpencil, eye shadow, eye line, lip stick, foundation, etc. The cycbrowpencil, eye shadow, eye line, and lip stick are such in nature that theymay be properly varied to suit the particular feeling created by a givenwoman on the particular day In contrast, the foundation does not need tobe varied very much day by day because it is intended to emphasize thecontour of a face by imparting light and shade roughly to the facethroughout the entire area thereof. Actually, however, women arespending much time in applying the foundation evenly to their faces andthey repeat this application any number of times daily because thefoundation is caused to peel off with the elapse of time on exposure towater or perspiration. By forming the foundation which inherentlynecessitates no such repetition of application in a constitution fixedto a degree enough to obviate the necessity for the daily repetition ofapplication under discussion, it is made possible to curtail the laborotherwise excessively spent concerning the cosmetic decoration.

Further, the foundation entails the complexity that it must be selectedto match the color of the skin of an individual person intending topurchase it in addition to the complexity which pertains to thenecessity for evenly applying it to the face. A great variety offoundations are marketed for the sake of ensuring natural finish ofcosmetic decoration. Undeniably the probability that such a consumerwill find a foundation perfectly fit for the color of her skin is low.

Another matter of concern for women is the slimming, i.e. reduction ofthe body weight. It is an evident fact that women fondly cherish thehope of becoming slim. Their wish at least to look slim existscertainly. In attempting to materialize this wish to look slim, they areallowed to utilize the technique of foundation mentioned above. That is,by applying a proper terminator of light and shade to arms and logs andemphasizing the parts of light and shade thereon, it is made possible tomake a body look beautiful in harmonious modulation. The method called“body makeup” which recent actresses and models are exercising as duringthe course of filming constitutes itself the technique of foundationjust mentioned. This method implies daily application of a foundation toarms and legs. Since the fulfillment of this method entails considerabletrouble, it is nearly impossible for women at large to stick to themethod faithfully.

The present invention has been perfected based on the conceptillustrated above. It is aimed at providing a technique for cosmeticdecoration which easily obtains the effect based on the same terminatorof light and shade as is attained by the application of a foundation,enables the resultant beautiful state to last for a fixed number of dayswithout entailing any collapse due to exposure to water or perspiration,and promises natural finish of the cosmetic decoration, therebyalleviating the burden of cosmetic decoration and easily bringing theeffect of enabling a user to look thin.

Disclosure of the Invention

The present inventor has taken notice of the fact that as an agency forimparting light and shade to the skin and, at the same time, enablingthe effect to last for a fixed number of days, the familiar naturalphenomenon which is known as “suntan” originating in the deposition ofmelamine pigment exists and has eventually conceived of an idea that theproblems mentioned above are solved by utilizing this naturalphenomenon. The present inventor has pursued a further study based onthis idea and has consequently perfected a method which, in performingcosmetic decoration targeted at imparting light and shade to the surfacecolor of the skin, attains the cosmetic decoration by enlarging thedegree of pigment deposition on the skin in the area requiring to assumea darker color and imparting light and shade to the surface color of theskin. Since the method for cosmetic decoration according to thisinvention which will be described herein below utilizes the depositionof pigment on the skin, it is at a great advantage in not only enablingthe light and shade imparted to the skin to last for several weeks as aunit without being disturbed by perspiration or water but also findinggeneral acceptance among woman because the method takes advantage of thepopular phenomenon found in daily life. According to the presentinventor's study, this method of cosmetic decoration has a furtheradvantage. Specifically, when the skin is endowed with light and shadeby this method of cosmetic decoration, the light and shade spontaneouslybecomes very natural in conformity with the tinge inherent in the skinof an individual person and ultimately gives rise to far more naturalfinish than is obtained by using any other foundation.

Several methods are available for the purpose of varying the degree ofdeposition of pigment in different areas of the skin. For example, thedegree of pigment deposition in different areas of the skin can bevaried by irradiating the skin with proper light. To be more specific,when the skin is irradiated with light other than the laser beam, thedeposition of pigment can be caused to varying degrees in differentareas of the skin by irradiating the areas of the skin requiring toacquire a darker color with the light in a proportionately larger dosagethereby causing the deposition of pigment to occur in varied degrees inthe different areas of the skin. In other words, this method consists inimparting light and shade to the surface color of the skin by causingthe skin to be burnt by the sunlight to varying degrees in differentparts thereof thereby inducing the suntan (browning) proportionately tothe varying degrees of the sunburn.

The suntan of the nature described above is produced irrespectively ofdistinction between visible light and invisible light, despitedifference in degree. The term “light” as used in this inventionembraces both visible light and invisible light. The suntan as generallyknown can be produced by using the ultraviolet light, for example. Thesuntan can occur when the skin is irradiated with light of anywavelength such as, for example, visible light, ultraviolet light, andfar infrared rays. In terms of the ease with which the suntan isproduced, however, it is considered most practical to use theultraviolet light.

For the purpose of varying the degree of pigment deposition in differentareas of the skin by the exposure to light other than the laser beam, itsuffices to vary proportionately the dosage of the light on the skin inthe different areas. That is, by irradiating the parts of the skinexpected to acquire a darker color with the light of a larger dosage, itis made possible to vary properly the degree of pigment deposition indifferent areas of the skin. Though the kind of means to be adopted forvarying the dosage of the light is irrelevant in this case, thevariation may be attained by varying the wavelength of light, the doseof light per unit area, the time of irradiation, etc. In this case, oneof such elements may be varied or two or more elements may be varied.Among other elements available for the variation, the variation of thedose of the light per unit area and the variation of the time of lightirradiation in different areas of the skin prove particularlyadvantageous in terms of ease of execution. These two means find utilityin a wide range because they can be implemented by using the sunlightand can effectively utilize both natural light and artificial light.

The variation of the dose of light per unit area can be effected, forexample, by such a simple means as covering parts of the face withadhesive tape or by using a decorative aid furnished with a cover forhiding prescribed areas of the skin as described herein below. In thiscase, when the cover in the decorative aid is so formed as to alloweasier passage of light in portions corresponding to the areas of theskin expected to acquire a darker color, the amounts of light allowed toirradiate different areas of the skin can be adjusted as expected bysimply projecting light on the skin through the cover placed on theskin. Specifically, by gradationally varying the transparency of thecover to light in different portions of the cover or by deletingportions of the cover in the manner of openings, it is made possible toobtain a cover which is capable of manifesting the effect mentionedabove. To be more specific, an adhesive tape which is provided withopenings formed like slits can be effectively used in forming slenderhighlight zones in specific portions of the skin. The variation of thedosage of light by the variation of the time of light irradiation can bealso accomplished by the decorative aid furnished with the cover. Thecover in this case is preferred to consist of a plurality cover bodiesadapted to hide prescribed ranges of the skin. Then, by sequentiallyremoving these cover bodies while keeping the skin irradiated with lightmeantime, it is made possible to vary the time of light irradiation indifferent areas of the skin. Otherwise, the variation of the dose oflight per unit area can be effected in the same manner as describedabove by using a projector which is provided with a light source adaptedto emit a light capable of causing pigment deposition on the skin and afilter adapted to transmit the light from the light source. The filterin this case, when adapted to vary the transmittance thereof to light indifferent portions thereof or given the partial deletion describedabove, enables the light emitted to the skin positioned at a prescribeddistance from the light source to irradiate the areas of the skinexpected to acquire a darker color more than the other areas.

Though the description, as given above, concerns the case of using lightother than the laser beam, this invention also contemplates varying thedegree of pigment deposition in different areas of the skin byirradiating the skin with the laser beam. The theory for the applicationof the laser beam to the method for cosmetic decoration of the presentinvention is not so simple as in the case of using light other than thelaser beam as described above. In the case of irradiating the skin withthe laser beam, not only the dosage of the laser beam allowed toirradiate the skin but also the time for irradiating the skin with thelaser beam have a large effect on the degree of pigment deposition onthe skin. When the time of irradiation of the laser beam per round isshorter than the thermal relaxation time of the target pigment (the timerequired for one half of the absorbed thermal energy to completemigration into the ambient texture), the irradiation is enabled toinduce omission of pigment instead of deposition of pigment. The Qswitch oscillation ruby laser is disposed to produce pigment omission inthe case of a high output and pigment deposition in the case of a lowoutput. In the case of projecting the laser beam to the skin for thepurpose of varying the degree of pigment deposition in different areasof the skin, therefore, the irradiation is enabled not only to promotethe pigment deposition on the skin but also to induce omission ofpigment in certain areas of the skin. Since the use of the laser beammakes it possible to produce omission of pigment which impedes pigmentdeposition in certain areas of the skin, it may be enabled to vary thedegree of pigment deposition in different areas of the skin. Further,the method which uses the laser beam at all makes it possible to imparta brighter color to certain areas of the skin and, at the same time, adarker color to other areas of the skin and, therefore, brings theadvantage of greatly widening the contrast between light and shade indifferent areas of the skin as compared with the case of utilizing thedeposition of pigment exclusively. This is not the only advantage thatis derived from using the laser beam. The fact that the variation ofpigment deposition is allowed to occur in a large degree because of theuse of the laser beam even when the time of irradiation of the skin isshort may be cited as another advantage. Thus, the use of the laser beamresults in successfully decreasing the burden imposed on a person whoexercises cosmetic decoration in accordance with the method of thisinvention. Incidentally, since the laser beam used in imparting lightand shade to the skin enables the boundary between light and shade toappear more distinctly, the impartation of light and shade can beapplied to such narrow areas as are involved in the application of eyeline or eye shadow.

For the laser beam under discussion, carbon dioxide gas laser, yaglaser, alexandrite laser, etc. can be used besides the ruby lasermentioned above. The laser bean does not need to be particularlydiscriminated on account of the kind. The irradiation of the skin withthe laser beam is generally carried out by causing the laser beam toscan a prescribed area of the skin. The degree of pigment deposition indifferent portions of the skin can be varied, for example, by varyingthe density, frequency, etc. of the scanning actions performed indifferent areas of the skin or by varying the wavelength of the laserbeam. As regards the emission of the laser beam, the act of varying thedegree of pigment deposition in different portions of the skin by usingthe decorative aid provided with the cover mentioned above may well berated as a preferred embodiment of the laser irradiation.

Besides the use of the light in the manner described above, theimpartation of light and shade to the surface color of the skin can beeffected by using a pigment deposition promoting agent for promoting thedeposition of pigment on the skin or the use of a whitening agentinhibiting pigment deposition on the skin. That is, by applying thepigment deposition promoting agent to the areas of the skin expected toacquire a darker color or by applying the whitening agent to the areasof the skin expected to acquire a brighter color, it is made possible tovary the degree of pigment deposition between these areas and otherareas and impart variation to the light and shade of the surface colorof the skin. Naturally, the whitening agent and the pigment depositionpromoting agent mentioned above can be used in combination. As thepigment deposition promoting agent proper in this case, such chemicalagents as psoralen which augment propagation of pigment cells andformation and secretion of melamine pigment and such chemical agents asdihydroxy acetone which induce deposition of pigment in cuticles by adifferent mechanism are usable. The melamine itself can be used as apigment deposition promoting agent. Particularly when it is used incombination with such a chemical agent as liposome which promotes theseepage of melamine into the skin, the effect of interest is exalted. Asconcrete examples of the substance that is usable as the whiteningagent, chemical agents possessed of the thyrosinase inhibiting activityeffective in lowering the propagation and activation of pigment cellsand inhibiting the synthesis of melanine pigment and chemical agentspossessed of the endoserine inhibiting activity are conceivable. Morespecifically, γ-oryzanol, urocanic acid, titanium dioxide, oxybenzone,oxybenzone, salicylic acid, glycolic acid, α-hydroxy acid, linoleicacid, pionine, cysteine, glutathione, phenols, nitrofuran derivatives,ascorbic acid and derivatives thereof, compounds possessed of a SH group(glutathione, cystine, etc.), hydroquinone and dervatives thereof(hydroquinone monobenzyl ether, albutin, etc.), amines, kojic acid andderivatives thereof, oil-soluble licorice extract, mercuric chloride andderivatives thereof, PMH, vitamin A acid and derivatives thereof,azelaic acid, macranine, saran, methionine, lecithin, tranexainic acid,RIKIRICHIN, and endoserine inhibitor may be cited.

For the application of the pigment deposition promoting agent or thewhitening agent to the skin, it suffices to apply it directly to theskin. Alternatively, a pack which is formed of a sheet adapted to beused as applied to the skin and has the parts of the sheet correspondingto the areas of the skin requiring to acquire a darker color coated orimpregnated with a pigment deposition promoting agent capable ofpromoting deposition of a pigment or the parts of the sheetcorresponding to the areas of the skin requiring to acquire a brightercolor coated or impregnated with a whitening agent capable of inhibitingdeposition of a pigment may be used. The pack of this construction isadvantageous because it enables a pigment deposition promoting agent ora whitening agent to be easily and accurately applied to the necessaryareas of the skin. In the sense that deposition of a pigment or omissionof a pigment is effected with high accuracy in each of the specifiedareas of the skin, the method of interest can be applied instead offacial makeup to the impartation of light and shade to narrow areas ofthe skin. A tape which has a pigment deposition promoting agent or awhitening agent applied as incorporated in a tackifier to the sidethereof intended to contact the skin may well be rated as advantageousin the sense that it can be stably fixed to the skin. The tape havingthe whitening agent applied thereto in the form of slender stripes inthe direction of length, for example, affords a great convenience forthe formation of highlight zones on the face. A sole pack which isformed by combining a pack coated or impregnated with the pigmentdeposition promoting agent and a pack coated or impregnated with awhitening agent is effective in further exalting the contrast of lightand shade concerning the surface color of the skin.

BEST MODE OF EMBODYING THE INVENTION

Now, preferred embodiments of this invention will be described belowwith reference to the drawings annexed hereto. In the description of thepreferred embodiments, like parts will be denoted by like referencenumerals to avoid repetition of description.

First Mode of Embodiment

As the first mode of embodiment, the method for cosmetic decoration willbe described which comprises outlining a T zone against the surface ofthe face thereby obtaining the same effect as in performing the facialdecoration resorting to proper variation of the application of afoundation.

This method of suntan makes a rule of effecting cosmetic decoration byusing a decorative aid 2 which is provided with a mask 1 as a cover.This mask 1 has the T zone 4 of a face which is an area expected toassume a brighter color than in any other area and the portion whichcorresponds to the malar bone formed of a raw material impervious to theultraviolet light and the other portions formed of a raw materialpervious to the ultraviolet light. It further has the portionscorresponding to the opposite lateral sides of a face which are theareas of the skin expected to assume the darkest color among otherportions pervious to the ultraviolet light formed of a raw materialtransparent to the ultraviolet light. In short, this mask 1 has theportions thereof corresponding to the areas of a face requiring toemphasize the height formed of a raw material having proportionately lowtransparency to the ultraviolet light. The boundary between the portionpervious to the ultraviolet light and the portion impervious to theultraviolet light is gradated to prevent the contrast between light andshade from becoming unnatural. The mask 1 is further provided with afixing means 3 (refer to FIG. 1). to the ultraviolet light. The boundarybetween the portion pervious to the ultraviolet light and the portionimpervious to the ultraviolet light is gradated to prevent the contrastbetween light and shade from becoming unnatural. The mask 1 is furtherprovided with a fixing means 3 (refer to FIG. 1).

Now, the method of cosmetic decoration which uses this decorative aid 2.The wish to get a suntan by using this mask 1 is accomplished by firstcovering the face with the mask 1 and then fixing the mask 1 to the headwith the fixing means 3. The face in the state consequently assumed isexposed for a prescribed time to the light of an ultraviolet lamp or thelight such as sunlight which contains an ultraviolet light.

When this exposure to the light is made, the dosage of the ultravioletlight is eventually differentiated between the area of the skincorresponding to the portion of the mask 1 having high transparency tothe ultraviolet light and the other area because this area receives theultraviolet light in a larger amount per unit area. As a result, theopposite lateral sides of the face which have received a larger dosageof the ultraviolet light manifest the effect of the suntan strongly andthe T zone which has received a smaller dosage of the ultraviolet lightremains in a white state as the highlight zone and the intermediate partbetween these two different areas assume a state gradated from a lightcolor to a dark color. Though the present mode of embodiment, asdescribed above, uses the cover 1 which hides the entire area of theface, for example, this invention allows the cover 1 to hide only partof the face.

Second Mode of Embodiment

Now, the second mode of embodying this invention will be described belowwith reference to FIG. 2. This mode of embodiment, i.e. a method forcosmetic decoration which produces the effect of making a leg lookslender by strongly depositing a pigment on the opposite lateral sidesof the leg and, at the same time, leaving the front side of the legwhite will be described.

In this mode of embodiment, the suntan is produced by using a suntan aid2 which is provided with a cover 1 formed in a cross section roughlyresembling the letter U along the front side contour of a leg. Thiscover 1 is formed of a raw material impervious to the ultraviolet lightand is composed of five cover pieces 1 a-1 e separated along thelongitudinal direction thereof.

Now, the method for getting suntan by using this suntan aid 2 will bedescribed below. The wish to get suntan by using this suntan aid isfulfilled by first fitting the cover 1 on the leg. The cover 1 isadapted to avoid covering the lateral sides of the leg. The leg in theconsequently assumed state is exposed to the ultraviolet light on thefront side and the lateral sides thereof. In this case, only the lateralsides of the leg are irradiated with the ultraviolet light. After theexposure to the ultraviolet light is continued for a fixed time, the twocover pieces 1 a, 1 e which are positioned on the opposite outer sidesare removed. Then, the leg in the consequently assumed state is exposedto the ultraviolet light. In this case, not only the lateral sides ofthe leg but also the areas of the leg which have been hidden by thecover pieces 1 a, 1 e are exposed to the ultraviolet light. Then, afterthe exposure to the ultraviolet light has continued for a fixed time,the cover pieces 1 b, 1 d positioned at this time on the opposite outersides are removed and the leg in the consequently assumed state isexposed to the ultraviolet light. In this case, the whole area exceptingthe part of the skin hidden by the cover piece 1 c positioned on thefront of the leg is fated to be exposed to the ultraviolet light. Whenthe deposition of pigment is caused in this manner, the portions of theleg on the opposite lateral sides which have been exposed to theultraviolet light for a long time are strongly sunburnt and the frontportions of the leg remain white. According to this method, the portionsof the skin binding the cover pieces 1 a-1 e are fated to produceboundary lines, though slightly, due to variations in the degree ofsuntan. These boundary lines pose no particular problem because they arefaded in a matter of one to two days.

Third Mode of Embodiment

The projector as the third mode of embodiment of this invention will bedescribed below with reference to FIG. 3. FIG. 3 illustrates a projector10 which combines a projecting part 11 and a filter 12. This projector10 has built therein a light source (not shown) serving the purpose ofemitting a light containing the ultraviolet light. The filter 12 isadapted to pass the light emitted from the light source mentioned aboveand meanwhile control the light irradiating the face positioned at aprescribed distance from the projector 10 so as to increase the amountof the light reaching the lateral side parts of the face which are theareas expected to assume a darker color. Incidentally, this filter canbe manufactured from an image portraying an ideal light and shadepattern. Alternatively, it can be manufactured by the white-to-blackinversion of a picture obtained by actually photographing a personendowed with an ideal light and shade pattern.

Fourth Mode of Embodiment

The fourth mode of embodiment of this invention will be described withreference to FIG. 4. Illustrated in FIG. 4 is a pack 20 of the shape ofa tape adapted to impart light and shade to a leg. This pack 20 isformed of a sheet 21 to be used as applied to the front side of a leg.The sheet 21 is coated on the side thereof fated to adhere to the leg,though omitted from illustration, with hydroquinone as a whiteningagent. Further, the peripheral part of the surface of the sheet 21destined to adhere to the leg is provided along the curve thereof withan adhesive tape adapted to adhere to the leg. When this pack 20 isapplied fast to the leg and then left standing for a while, the skin ofthe front of the leg assumes a bright color and the leg, owing to thedifference of color from the opposite lateral sides thereof, is made tolook slender. The method of using the whitening agent in the mannerdescribed above fits a person whose skin inherently has a dark colorand, in this respect, differs from the first—third modes of embodimentwhich fit persons whose skins inherently have a dark color.

Fifth Mode of Embodiment

The fifth mode of embodiment of this invention will be described withreference to FIG. 5. FIG. 5 illustrates a pack 20 to be used for thepurpose of making the T zone stand out in appearance. Since this pack 20is used as applied fast to the T zone, it incorporates therein a sheet21 which is formed in a shape substantially resembling the letter T. Theside of this sheet 21 destined to adhere fast to the skin is impregnatedwith psoralen as a pigment deposition promoting agent and hydroquinoneas a whitening agent. Specifically, the part of the sheet 21 indicatedas a is impregnated with the pigment deposition promoting agent and thepart thereof indicated as b is impregnated with the whitening agent. Byrepeating the act of fastening this pack to the T zone and allowing itto stand thereon for a while, therefore, the forehead and the bridge ofthe nose are made to stand out in a bright color and, at the same time,the opposite lateral sides of the nose are made to assume a dark color,with the result that the face will appear to have a shapely nose.

Sixth Mode of Embodiment

The sixth mode of embodiment of this invention will be described withreference to FIG. 6. This method concerns a technique for varying thedegree of pigment deposition in different areas of the skin by using alaser beam. The method of this mode of embodiment, in irradiating theskin with the laser beam, uses a decorative aid 2 which is provided witha body suit 1 as a cover as illustrated in the diagram. The decorativeaid 2 to be used in this method is prepared in two types as illustratedin the diagram. First, the decorative aid 2 illustrated on the left sidein the diagram is formed of a transparent raw material adapted to resistpassage of light more in the part of the skin requiring to assume adarker color. Then, the decorative aid 2 illustrated on the right sidein the diagram is formed of a transparent raw material adapted to resistpassage of light more in the part of the skin requiring to assume abrighter color. In the diagram, both the decorative aids 2 areillustrated so as to appear in a denser black color in the partresisting passage of light more.

The method for cosmetic decoration in this case is as follows. First, aperson about to put up cosmetic decoration is made to wear the body suitillustrated on the left side in the diagram. The laser set under suchconditions as to induce omission of pigment in the skin is made toirradiate the subject in the consequently assumed state so as to scanthe whole body of the subject. This body suit is adapted to resistpassage of light in the area of the skin requiring to assume a darkcolor as described above. The laser beam capable of inducing omission ofpigment, therefore, is fated to reach only the area of the skin thatrequires to assume a bright color. Thus, the degree of pigmentdeposition decreases in the part of the skin requiring to behighlighted. Then, the person about to make cosmetic decoration is madeto wear the body suit illustrated on the right side in the diagram. Thelaser set under such conditions as to induce deposition of pigment inthe skin is made to irradiate the subject in the consequently assumedstate so as to scan the whole body of the subject. This body suit 1 isadapted to resist passage of light in the area of the skin requiring toassume a bright color as described above. The laser beam capable ofinducing omission of pigment, therefore, is fated to reach only the areaof the skin that requires to assume a dark color. Thus, the degree ofpigment deposition increases in the area of the skin requiring to assumea dark color. Incidentally, since the part of the body suit 1illustrated on the right in the diagram which does not pass the laserbeam partly overlaps the part of the body suit 1 illustrated on the leftin the diagram which passes the light, the surface color in part of thearea of the skin is fated to remain intact. According to the methoddescribed above, therefore, proper gradation is imparted to the boundarybetween the area made to assume a dark color and the area made to assumea light color by the exposure to the laser. By using the method ofcosmetic decoration in the present mode of embodiment, it is madepossible to attain in a very short span of time the same effect as isobtainable by performing a body make which normally last over severalmonths.

Industrial Applicability

The method for cosmetic decoration contemplated by this inventionutilizes the deposition of pigment as described above. The light andshade which is imparted by this method lasts for several days withoutbeing affected by perspiration or water, notwithstanding it brings thesame effect as the foundation. Thus, this method can greatly alleviatethe time and labor spent in the cosmetic decoration. Further, the lightand shade obtained by the deposition of pigment assumes a perfectlynatural tint because it is based on the color of the skin of theindividual person. This method, therefore, is at an advantage inalleviating the burden of cosmetic decoration and allowing the effect ofmaking the subject look slim to be more easily and naturally obtainedthan when the conventional foundation is used. Then, by using thedecorative aid, projector, and pack according to this invention, it ismade possible to attain the effect mentioned above more easily andaccomplish the alleviation of the burden on the cosmetic decoration to agreater extent.
